I've got a Kenwood KDC-W707 head unit which has a D-MASK facility. I was doing some work on my car earlier today and disconnected the negative battery terminal. When I re-connected it, the D-MASK had flipped back on itself even though the panel is actually detached. I've tried pressing in the correct corner of the unit to get the thing to turn round but it isn't having any of it.
Is this some kind of built in security measure that Kenwood have put in place? If you've got any ideas, please let me know as I'm about to pull my hair out here!
Why are things with cars never straight-forwards!!!
